Palladium Nanoparticles/Graphitic Carbon Nitride Nanosheets-Carbon Nanotubes as a Catalytic Amplification Platform for the Selective Determination of 17α-ethinylestradiol in Feedstuffs.

A new kind of nanocomposite, graphitic carbon nitride (g-CN)-carbon nanotubes (CNTs), has been synthesized via solid grinding, and followed by thermal polymerization process of melamine and CNTs. Pd nanoparticles were loaded on the as-prepared nanocomposite by the self-assembly method. The Pd/g-CN-CNTs nanocomposite exhibited excellent electrocatalytic activity toward the oxidation of 17α-ethinylestradiol (EE2), and compared with other detection methods of EE2, such as HPLC, this detection platform does not need the samples for further purification processing.

[Protective actions of acupoint magnetic medicated plaster therapy on hepatic function in the patient of cirrhosis after hepatitis].

Objective: To observe the therapeutic effect of acupoint magnetic medicated plaster therapy on cirrhosis after hepatitis.

Methods: One hundred and twenty patients with cirrhosis after hepatitis were randomly divided into 2 groups. The control group (n=60) were treated by the hepatic protective therapy (diammonium glyeyrrhiznate, Silymarin, compound Tanshin, vitamin E), and the treatment group were treated by the liver-protective therapy and acupoint magnetic medicated plaster therapy, for 2-6 therapeutic courses.
